If there is a large group of people who use a term like "anti-fascist" as a tag line it no longer is a literal representation of the words. Just like how you wouldn't say that a guy rolling coal in a lifted pickup with a confederate flag and an AR mounted in the window who calls himself a "freedom fighter" is literally fighting for freedom.

Otherwise you will just be talking past people who are interpreting it to mean something else. Which of course you are free to do if you don't think what you are trying to say has enough value to be worth avoiding the miscommunication.
